To a ham it may concern: shaft, H, that is journal'ed vertically within Be known that I, JOHN G. BUZZELL, of suitable bearings near the rear end of the ta- Lyn u the county of Essex, and in the State ble F. The shaft H is driven from a counterof achusetts, have invented certain new shaft, I, ,Whichis journaled horizontallybeeful Improvements in Machines for neath the table F, and is connected with said 1 and Whitening Leather; and doshaft H by means of two bevel-gears, I and declare that thefollowing is a full, K, that are secured upon said shafts in such I d exact description thereof, reference position as to cause them. to mesh together. ad to the accompanying drawings, The skins to be operated upon are placed; a part of this specification, in whichupon the tableF andpassed beneath the diskA, e 1 is a perspective view of my maandarepressed againstthe abrading-surfaceof arranged for use.

From the fan N a duct, P, exwhic secured upon and revolves with a tends forward to and slightly over the rear 7 edge of the disk A, and into such duct all dust and particles of leather will be drawn by the 'suction of said fan.

The machine thus constructed enables leather to be shaved more evenly and with less trouble than would be possible by use of a machine having abrading-rollers, while the abradingsurface can be more quickly and perfectly renewed than can the surface of said rollers.

When used for shaving or whitening leather, a plane or convex disk is employed; but for use in dressing the shanks of boots and shoes, or for other like irregular surfaces, either the concave or convex faced disks may be employed to advantage.

I am aware that machines have before been used in which the skin being operated upon was pressed against the abrading-surface by means of a movable support, and therefore do not claim, broadly, such construction.

Having thus fully set forth the nature and merits of my invention, what I claim as new is- 1. In a machine for shaving and whitening leather, the combination of the disk A, covered upon its face with abrasive material, and arranged to rotate in a horizontal plane, the

slotted supporting-table F, and the bar L arranged to be moved positively and vertically by means of the lever M, whereby any portion of the surface of askin may be raised into contact with said disk at the will of the operator, substantially as and for the purpose specified.

2. In combination with the presser-bar L, the set-screw l, passing through the lug lof said bar, and arranged to impinge upon a fixed stop, so as to limit the upward motion of said bar, substantially as and for the purpose shown.

3. The hereinbefore-deseribed machine, consisting of the abrasive disk A, shafts D and I, table F, arm E, pulley d, belt G, hand-wheel h, bar L, having the .lug Z and set-screw l, treadle M, fan N, belt 0, and duct P, said parts being combined to operate in the manner and for the purpose substantially as shown and described.

In testimony that I claim the foregoing I- have hereunto set my hand this 13th day of August, 1877.
